The pilot can use full Mode I capabilitywith Mode II and Mode III as backups.LANDING SEQUENCEThe landing sequence begins when the aircraft isat the marshaling point (fig. 9-2) under control of thecarrier air traffic control center (CATCC). Thesequence is in two phases: approach and descent.Flight from the marshaling point to the radaracquisition window is the approach phase. Flightfrom the radar window to touchdown is the descentphase. Transition from the approach phase to thedescent phase is done with a minimum of switchingoperations to reduce pilot task loading.MODE I LANDING OPERATIONFigure 9-3 shows the Mode I landing sequence.The sequence begins when the aircraft is at themarshaling point.
